Definitely don't have kids with him if he can't cope with crumbs or things being broken and left while you handle more important things.
Kids are messy, it's impossible to keep a clean home without wearing yourself thin, and still make space for a relationship.
Kids also break things. It's just a natural part of their exploration of the world.
Cleaning schedules go out of the window.
And that's once the kid is born. If you have a difficult pregnancy your standards will drop because you'll be in survival mode.
I am not calling him a bad man.
I am an autistic woman and I have to have things a certain way, and there were so many changes I was not prepared for that it destroyed my mental health being pregnant, sick, unable to keep to my routines and schedules, not realising how much of a sensory nightmare all things baby can be in the early days... It takes a toll on your partner too.
You can't just suddenly stop being autistic because you have a child. You can't suddenly stop having black and white thinking, mental rigidity and inflexibility, sensory issues, communication issues or develop an ability to remain zen in situations that cause emotional dysregulation.
I'm really sorry to be blunt OP.
I can't tell you how down I have felt at the dissolution of my relationships because the criticisms I've received have been because of things I can't control like my rigid thinking, even though I can still empathise and understand how difficult it can be to live with.
If you do decide to move in together make sure you always have a place to go to if it doesn't work out.
